ok funny thing, i thought that my injectors were bad so i bought two from a local and put them in my car, these injectors that i bought were from a later model s4, and i have and earlier model, so there are a couple things that i have noticed that this does,
idle: rich not all the way, but close
Accel: RIch, wot
Cruise: No open close loop, just rich,
up hill: open closed loop

there is no open closed loop.
it is either open loop, or closed loop.
closed loop uses O2 sensor data to adjust the fuel mixture. (computer -> fuel mix -> combustion -> exhaust gasses -> sensor -> computer -> fuel mix... see the loop?)
open loop rely's on predetermined maps and just dumps in the gas without sensor input. (computer-> fuel mix -> combustion -> exhaust gasses. the loop doesnt come back to itself)

If they plugged in without any problem they are probably the proper resistance... however, if you put TII injectors in an NA you will get the symptom you described. They are 550 cc instead of 460 cc.

I ran low imp secondary injectors on my high impedance 88 for 30,000 miles. I don't recommend it but it did work. Had to file the locating pin off the l.i. injectors to get it to fit.
